APPARATUS FOR MANUFACTURING GAS.

SPECIFICATION forming part of Letters Patent No. 637,856, dated November as, 1899 Application filed August 9, 1897.

To all whom it may concern:

Be it known that I, LEVI S. DAVIS, a citizen of the United States, residing at Oanisteo, Steuben county, New York, have invented certain new and useful Improvements in Gas- Generators, of which the following isa specification.

This invention relates to certain new and useful improvements in apparatus for the manufacture of gas, having for its object to improve such apparatus generally and to prevent waste of the hydrocarbon liquid employed in the manufacture and the formation of lampblack and tarry matter. With these objects in view the invention consists in the method and apparatus hereinafter more fully described.

In the accompanying drawings, illustrating the invention, Figure 1 is a longitudinal sectional elevation of theimproved apparatus used in carrying the invention into effect, and Fig. 2 is a detail sectional view of the genera tor.

The apparatus employed may be constructed in various ways; but preferably it is built of masonry to form a generator A and a fixing-chamber B, which latter communicates through a pipe awith a suitably-constructed scrubber. (Not shown.)

The generating-chamber A is preferably contracted at its upper end and is provided with the usual peep-holes a and at its lower end with a coal-bed to support a charge of coal 1), which is maintained by means of a suitable feeder c, and an.air-pipe (1, leading from a blower C, is arranged to deliver an air-blast upwardly through the coal-bed. EX- tending centrally through the body of coal to a point immediately above the same is a pillar of masonry, through which extends an oil-pipe from which leads a series of radial branch pipes f, terminating at the top of the pillar in spray-nozzles f adapted to direct a spray of heated hydrocarbon vapor upwardly through the generating-chamber, but out of contact with the walls thereof. The air-pipe d likewise extends through the pillar or wall and has leading therefrom a series of horizontal radially-arranged branch pipes d, which open into the generating-chamber at points Serial No. 647,591; (No model.)

just above the base of the pillar and deliver air uniformly to the coal-bed.

Heretofore it has been customary to introduce a hydrocarbon vapor horizontally into a generating-chamber above the coal-bed or to introduce it horizontally into the chamber from a central partition; but as it is necessary that such vapor shall be thrown entirely across the chamber in order to bring it into intimate contact with the entire volume of gases from the coal it has been impossible to prevent the vapor from striking the opposite walls and breaking up, resulting in the burning of the vapor and the formation of lampblack and of tarry substances, and thus increasing the consumption of the vapor and impairing the quality of the resulting gas. These disadvantages are overcome by the use of the present invention, as by the introduction of the hydrocarbon into the generating chamber with the current of gases in a vertical spray it is caused to flow upwardly in the direction of flow of the gases from the coal without disturbing such flow and without being thrown against the inner walls of the chamber. A very much smaller quantity of vapor is thus required in the manufacture of gas, and the quality of the gas is materially improved.

The fixing-chamber B is formed with a sinuous channel 6, which communicates at the upper end with the generating-chamber and through the pipe at with a scrubber or gasometer, as desired.

The oil-supply pipe extends in coils through the walls of the fixing-chamber in close proximity to the channel c in order to heat the oil before it is introduced into the generatingchamber A and this pipe communicates with a pump D, by means of which the oil is forced through the pipe into the generating-chamber. The pump in turn communicates with a suitable oil-supply tank E, and intermediate this tank and the pump is a measuring vessel F, from which water is introduced into the oil previous to its being drawn into the pump 5 IOO I eat 85% late the quantity of fluid flowing through said pipe to the generating-chamber.

By the introduction of water into the oil the quality of the gas is improved and the liability of the oil being burned is also lessened.

\Vithout limiting myself to the construction and arrangement of the parts shown and described, what I claim is 1. In an apparatus for the manufacture of gas, the combination of a generator and a fixing-chamber, an air-pipe communicating with the lower end of the generator and with a blower, an oil-supply pipe provided with a nozzle arranged centrally of the generatingchamber to direct a heated hydrocarbon vapor vertically through the chamber, and a measuring vessel communicating with the oil-supply pipe through a valve-controlledpassage, substantially as described.

2. In an apparatus for the manufacture of gas, the combination of a generator and a fixing-chamber, an air-pipe communicating with the lower end ofthe generator and with a blower, an oil-reservoir, and an oil-supply pipe communicating therewith and provided with a nozzle arranged centrally in the generating-chamber to direct a heated hydrocarbon vapor vertically upward through the chamber, substantially as described.

3. In an apparatus for the manufacture of gas, the combination of a generator provided at its bottom with a pillar or wall, a series of oil-supply pipes extending through said pillar and opening into the generator, a source of oil-supply connected to said pipe, a series of laterally-extending air-supply pipes projecting through the walls of the pillar below the top thereof, and a fan or blower communicating with said air-pipes, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LEVI S. DAVIS.
